异构催化剂是一个新兴的催化领域,它越来越充满了炒作和真实的世界应用之间的斗争所带来的痛苦。受丰富而分散的太阳能和清洁水和能源等应用的启发,充足的动力为这种情况提供了背景。然而,实质性基本(例如,电荷转移,复合),工程(例如,观察到的速率,光子管理),和实际的障碍(例如,使用贵金属、竞争技术)的执行有限。在这篇综述中,这些都是概述,结合典型的策略进行改进,重点是使用半导体光催化剂的降解新兴的永远在水中的化学污染物。选定的永久性化学污染物类别包括(微)塑料、全氟烷基和多氟烷基物质(PFA)、硅氧烷和二氧杂环己烷。每一种都被确定为一种关键的或新出现的污染物,由于缺乏自然补救过程,它们在大气中积累时往往会广泛传播。对外地的建议和作出贡献的机会在整个报告中都得到强调,并作为对未来的展望的一部分。
Heterogeneous photocatalysis is an emerging area of catalysis increasingly fraught with pains caused by the battle between hype and real‐ world application. Inspired by abundant yet diffuse solar energy and applications such as clean water and energy, ample motivation has provided the background for this situation. However, substantial fundamental (e. g., charge transfer, recombination), engineering (e. g., observed rates, photon management), and practical barriers (e. g., use of precious metals, competing technologies) have limited implementation. In this review, these are all outlined, in conjunction with typical strategies for improvements, with an emphasis on the use of semiconductor photocatalysts for the degradation of emerging forever chemical contaminants in water. The selected classes of forever chemical contaminants are (micro)‐plastics, per‐ and polyfluoroalkyl substances (PFAs), siloxanes, and dioxanes. Each has been identified as a key or emerging contaminant and often travel widely while accumulating in the atmosphere due to the lack of natural remediation processes. Recommendations to the field and opportunities for contributions are highlighted throughout and as part of the outlook to the future.
